This paper addresses a real-life public patient transportation problem derived from the Hong Kong Hospital Authority (HKHA), which provides ambulance transportation services for disabled and elderly patients from one location to another.
The optimal waste collection and transportation routes derived from our analysis result in 59.12% reduction in travel distance along the routine collection road network followed.
The goal of this LCA study is to assess the environmental impacts related to the production and utilization of transportation biofuels derived from product gas upgrading when torrefied wood pellets, wood pellets, and straw pellets are used as feedstock.
In addition, to the best of our knowledge, there is no LCA study regarding the environmental performance of transportation biofuels derived from torrefied wood which considers the RED emissions targets.
The aim of this study was to use empirical data to investigate whether increasing a port's capacity of biomass for the production of transportation fuels derived from syngas, with torrefied wood pellets, wood pellets, or straw pellets as feedstock, offers environmental benefits.
Analysis showed that the high specific surface capacitance of the resultant carbons was mainly attributed to optimized pore size (0.7 1.2 nm) and the excellent rate performance should be principally due to the reduced ion transportation distance derived from the nanometer-scaled fibers.
The present study attempts to quantify the WTW life cycle GHG emissions for transportation fuels derived from five North American conventional crudes through the development of an LCA model called FUNNEL-GHG-CCO (FUNdamental Engineering PrinciplEs-based ModeL for Estimation of GreenHouse Gases in Conventional Crude Oils).
Liquid transportation biofuels derived from sustainable lignocellulosic biomass have the potential to significantly reduce greenhouse gas emissions relative to petroleum-derived fuels.
For example, transportation can be derived into water transportation, which can be derived further into boat transportation, cruise transportation, and ferry transportation.
Relative to liquid transportation-fuels derived from petroleum, biofuels derived from the pretreatment and enzymatic hydrolysis of lignocellulosic biomass offers many potential sustainability benefits.
